Total and Grand Total Count Direction (Count)
By default, the batch total and grand total count up during batch
processes. Count parameter allows this to change. When set to count
down, the batch total will count down from the preset to 0. When set to
count down, the grand total will count down from a set value to zero.
Analog Output Programming (AoutPr)
The Analog Output Programming menu is used to program the behavior
of the 4-20 mA output. The following parameters and functions are
programmed in this menu:
1. Source: Source for generating the 4-20 mA output (e.g. PV)
2. Overrange: Analog output value with display in overrange condition
3. Underrange: Analog output value with display in underrange condition
4. Break: Analog output value when loop break is detected
5. Max: Maximum analog output value allowed regardless of input
6. Min: Minimum analog output value allowed regardless of input
7. Calibrate: Calibrate the internal 4-20 mA source reference used to
scale the 4-20 mA output
Analog Output Source
The source for generating the 4-20 mA output may be assigned to the
rate/process variable, total, grand total, maximum or minimum value
reached by the rate/process, one of the set points, or the Modbus PV
input.
Analog Output Calibration
To perform the analog output calibration it’s recommended to use a
milliamp meter with a resolution of at least 0.1 µA to measure the output
current. The values saved internally during this procedure are used for
scaling the 4-20 mA output in the Setup menu.
